Justin Bieber's neighbor is sounding off on the pop star's egg-throwing antics. The unnamed homeowner, who claims the 19-year-old singer egged his house Thursday, says he can't imagine why the Biebs attacked him and his daughter. "We went to our outside balcony and saw [Justin] standing in my front yard, ripping eggs at my house," he said. "Then I called the sheriff." If charged, Bieber could face misdemeanor vandalism.
